Realizing a higherTfand hence a ductile state in a glass upon cooling requires either a slower relaxation process or faster cooling. As the relaxation process of a BMG forming liquid is an alloy specific and intrinsic property, only the cooling rate can act as a tool to enhance ductility. As...
hardness due to the removal of supersaturated carbon in solid solution. This effect might be the reason for the reduction in tensile strength by 32 MPa after bake-hardening. Thus, bake-hardening of the UFG DP steel leads to a strong increase in yield strength and little decrease of tensile ...
As-cast pure Zn has a hardness of only 37.9 HV, tensile strength of less than 40 MPa, yield strength of less than 30 MPa, and elongation of only 1.2 %; such poor mechanical properties are unsatisfactory for clinical application [23]. (ii) Zn has only a few slip systems, leading to ...
crack initiation was obtained by dividing the number of the corners with the generated cracks by the total number of the corners of indentations. The applied load was increased step-by-step and at least ten indentations were made for each applied load. The hardness was determined with Vickers...
