This book was released on 2018-07-05 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: Measurements of the ductile-brittle transition temperature of heavily doped silicon were carried out using indentation techniques. Diamond pyramid hardness tests were performed on the (100) face of heavily doped N-type and P-type and intrinsic silicon single crystals. Tests were performed over the range 200 C to 850 C and loads of 100 to 500 g were used. Samples were subsequently etched to reveal dislocation rosettes produced by indentation. Intrinsic silicon underwent a ductile-brittle transition at 660 C, P-type at 645 C and N-type at 625 C. Hardness values varied from 1.1 GPa at 700 C to 11.7 GPa at 200 C. Significant effects of hardness on doping were present only at the highest temperatures. Lower loads generally produced higher hardness but load did not affect the Ductile-Brittle Transition Temperature (DBTT). Fracture toughness values ranged from 0.9 MPa m(1/2) at 200 C to 2.75 MPa m(1/2) near the DBTT. Doping did not affect the fracture toughness of silicon. P-type doping increased the size of dislocation rosettes observed after indentation, but N-type did not, in contradiction of the expected results. Results are discussed in terms of the effect of doping on the dislocation mobility in silicon. Rybicki, George C. and Pirouz, P. Glenn Research Center RTOP 505-63-1A...

Available in PDF, EPUB and Kindle. Book excerpt: These volumes, 7 and 8, of Fracture Mechanics of Ceramics constitute the proceedings of an international symposium on the fracture mechanics of ceramic materials held at Virginia Polytechnic Institute and State University, Blacksburg, Virginia on June 19, 20 and 21, 1985. These proceedings constitute the fourth pair of volumes of a continuing series of conferences. The theme of this conference, as the previous three, focused on the mechanical behavior of ceramic materials in terms of the characteristics of cracks, particularly the roles which they assume in the fracture process. The 78 contributed papers by over 100 authors and co-authors represent the current state of the field. They address many of the theoretical and practical problems of interest to those concerned with brittle fracture. The program chairmen gratefully acknowledge the financial assistance for the Symposium provided by the EXXON Foundation, the Army Research Office, the National Science Foundation, and the Office of Naval Research. Without their support, this conference simply would not have been possible. The suggestions of Drs. J. C. Hurt, R. C. Pohanka, and L. Toth were particularly helpful in assuring the" success of this symposium. Special appreciation is extended to Professor J. I. Robertson, C. P. Miles Professor of History, whose presentation following the banquet on the American Civil War was very well received by the audience. Finally, we wish to also thank our joint secretaries, especially Karen Snider, for their patience and help in finally bringing these proceedings to press.

Download or read book Dynamic Fracture of Solar Grade Single Crystalline Silicon Wafers written by Meng Wang and published by . This book was released on 2019 with total page 142 pages. Available in PDF, EPUB and Kindle. Book excerpt: Crystalline silicon has attracted substantial attention for decades because of its large applications in solar cells and microelectromechanical systems. The high brittleness of silicon raises wide concerns since the failure of this semiconductor material increases the manufacturing cost and decreases the efficiency of the utilization of Si-based devices. Crack propagation of crystalline silicon is the main cause of catastrophic failure of silicon components. It has been intensively studied but is not fully understood yet due to intricate dynamic fracture behavior linked to small-scale phenomena. Therefore, the development of feasible methods to study the dynamic fracture, as well as the deeper understanding of fracture mechanism of crystalline silicon, are of paramount importance to improve the reliability and durability of Si-based systems for both industrial and scientific practitioners. In this work, dynamic fracture behavior of solar-grade single crystalline silicon wafers under mechanical loads was studied. We carried out fracture experiments on (001) silicon wafers using three-line or four-line bending apparatus under quasi-static loading. The entire fracture process was captured using a high-speed camera and was analyzed by the high-speed imaging technique. We studied the post-mortem fracture surface using a digital microscope, a laser scanning profilometer, as well as an atomic force microscope. The failure source of the silicon wafer was identified using fractographic analysis. Coupling the crack velocity measurement and fractographic analysis, we determined the crack front during dynamic crack propagation, which exhibits a velocity-dependent shape. We revealed the source of (110)-(111) cleavage plane deflection phenomena during high-speeding crack propagation under line-contact effects. Besides, jointly with the finite element simulations, we demonstrated how dynamics of the crack front is governed by the crystallographic direction-dependent dynamic fracture toughness. Finally, in comparison with the Wallner lines on the fracture surface, generated by linear perturbations of elastic waves on the crack front, we highlight the nucleation and strong nonlinear characteristics of out-of-plane corrugation waves, leaving specific markings that alter the surface roughness of asperity-free material.

This book was released on 2001-03-31 with total page 996 pages. Available in PDF, EPUB and Kindle. Book excerpt: The word tribology was fIrst reported in a landmark report by P. Jost in 1966 (Lubrication (Tribology)--A Report on the Present Position and Industry's Needs, Department of Education and Science, HMSO, London). Tribology is the science and technology of two interacting surfaces in relative motion and of related subjects and practices. The popular equivalent is friction, wear and lubrication. The economic impact of the better understanding of tribology of two interacting surfaces in relative motion is known to be immense. Losses resulting from ignorance of tribology amount in the United States alone to about 6 percent of its GNP or about $200 billion dollars per year (1966), and approximately one-third of the world's energy resources in present' use, appear as friction in one form or another. A fundamental understanding of the tribology of the head-medium interface in magnetic recording is crucial to the future growth of the $100 billion per year information storage industry. In the emerging microelectromechanical systems (MEMS) industry, tribology is also recognized as a limiting technology. The advent of new scanning probe microscopy (SPM) techniques (starting with the invention of the scanning tunneling microscope in 1981) to measure surface topography, adhesion, friction, wear, lubricant-fIlm thickness, mechanical properties all on a micro to nanometer scale, and to image lubricant molecules and the availability of supercomputers to conduct atomic-scale simulations has led to the development of a new fIeld referred to as Microtribology, Nanotribology, or Molecular Tribology (see B.
