探讨了合金元素W、B的加入对MoSi2合金发热体物理、化学性能的影响。通过对三种不同组分试样室温抗弯强度、相对体积密度的测试,对其显微组织、断口形貌和X射线衍射的分析发现,W、B元素的加入细化了晶粒,显著提高了材料的室温抗弯强度。
The effects of adding alloying elements W and B on the physical and chemical properties of MoSi2 alloy heating element were discussed. Through the tests of room temperature flexural strength and relative bulk density of three different components, the microstructure, fracture morphology and X-ray diffraction of the samples were analyzed. It was found that the addition of W and B elements refined the grains obviously Improve the room temperature bending strength of the material.
