]可以推测在界面处产生了FeAl金属间化合物.在如图12所示的测试点下,测试点间距100 μm,界面各点显微硬度变化如图13所示.由图13可知,界面上铝材一侧越靠近界面硬度越高,而钢材一侧界面处硬度越靠近界面,硬度越低.这表明6061铝材在冲击连接时发生加工硬化,界面处存在富Fe相,硬度最高;而钢材一侧,由于受到预成形及冲击连接,加工硬化层较厚,界面处存在富Al相,硬度最低[32]. 综合图10和......

.由于金属钴的价格昂贵,耐腐蚀性和耐氧化性相对较差,人们开发了新型粘结相成分的硬质合金,如采用Ni,Cr和Fe部分或全部取代Co,也有采用Ni3Al,NiAl,Fe3Al和FeAl等作为粘结相[54]. 硬质合金是由脆性硬质相和韧性粘结相组成的复合材料,因此硬质相和粘结相的化学成分都会显著影响硬质合金的疲劳性能.研究表明在循环载荷下,TiC基金属陶瓷和WC基硬质合金中的各相尤其是碳化物相的塑性会显著......
