Indentation size effect in microhardness measurements of Hg1-xMnxTe WANG Ze-wen(王泽温)1, 2, 3, JIE Wan-qi(介万奇)2, WANG Xiao-qin(汪晓琴)4 1. School of Materials Science...; Abstract: The effect of surface damaged layer and Te enrichment layer of Hg1-xMnxTe on the indentation size were studied experimentally. Based on the results, the indentation size effect (ISE......
Investigation of Adhesion and Fracture Toughness of Thermally Grown Oxide Scales by Interface Indentation Test P. Lours1,QI Yu-hong2,p. Bruckel1,ZHANG Zhan-ping2 (1.Research Centre on Tools... grown oxide scales for pure nickel were investigated using Vickers indentation technique. The nickel samples were oxidised at 1200℃ for 100h-600h. The crack length induced by Vickers indentation test......
J. Cent. South Univ. (2012) 19: 1175-1181 DOI: 10.1007/s11771-012-1125-z Finite element and experimental analysis of Vickers indentation testing on Al2O3 with diamond-like carbon coating ZHAI... indentation testing of the Al2O3 ceramic coated by diamond-like carbon (DLC) layer were conducted. The numerical analysis was implemented by a two-dimensional finite element (FE) axis symmetry model. FE......

%. The crack paths, generated by Vickers indentation on the polished surfaces of both composites, were analyzed from a fractal point of view to distinguish the possible toughening mechanisms involved. Quantitative evaluation of indentation cracks indicates that the crack deflection plays a more effective role. Cracks of the ATC composites show higher deflection angles and more deflections along the path......
