采用真空熔铸法制备不同硼含量铸锭，并加工成不同丝径的悪品，利用光恘显微镜、扫描电镜、电子拉力试悚机等分析手段对其物理性能和微观结构进行了悁究。结果表明，硼在铂中形成间隙固溶体，铂的晶格常数增大，产生晶格畸变，阻碍位错惕动，铂的强度得到明显强化，硼与铂形成合金后，使铂的晶粒得到细化，硼在铂中起到强化作用的同时惁使铂的脆性增加。
Using vacuum melting casting prepared different boron content ingot, and processed the ingot into different diameter samples by drawing technology, using optical microscope, scanning electron microscopy, electron tensile testing machine and other analysis methods to study the physical properties and microstructure of materials. Results showed that, boron in the platinum formation the interstitial solid solution, the lattice constant of platinum increased, and formed lattice distortion, hinder the dislocation motion, the strength of the platinum increased obviously, boron and platinum forming alloy, which made the grain of platinum refinement, boron in platinum have reinforcement effect as well as increase the brittleness of platinum.
