Standard tensile specimens were cast from a nickel-base partial denture casting alloy and subsequently fractured in a tensile stress testing machine. Fracture sites were subjected to scanning electron microscopy in order to determine the exact mechanism by which failure had occurred. A metallographic examination of prepared specimens was used to demonstrate the distribution of phases within the alloy.
标准拉伸试样由镍基局部义齿铸造合金浇铸而成，随后在拉伸应力试验机中断裂。对断裂部位进行扫描电子显微镜检查，以确定失效发生的确切机制。对制备好的试样进行金相检验，以展示合金中相的分布。
