Al–Ti–B master alloys (MAs) were SHS-produced from the elements taken in the amounts that would ensure the preparation of final combustion products (MAs) containing about 20, 25, and 30 mol % TiB2. Combustion products and the samples of commercial Al alloy doped with 0.2 wt % combustion-synthesized MAs were characterized by optical microscopy, XRD, SEM, and EDS. The effect of added MAs was explored by optical microscopy using Clemex Vision software to determine the ASTM grain size number (G) and percentage of intermetallic compounds in doped Al alloys. A higher microhardness (97.64 HV 0.05) was observed for the Al specimens doped with MA nominally containing 25 mol % TiB2.

SHS生产的Al–Ti–B中间合金:商业铝合金的性能

Al-Ti-B中间合金(MAs)是从所含元素中SHS生成的,其含量应确保制备最终燃烧产物(MAs)的含量约为20、25和30 mol%的TiB 2。用光学显微镜,XRD,SEM和EDS对燃烧产物和掺有0.2 wt%燃烧合成MA的商品铝合金样品进行表征。使用Clemex Vision软件通过光学显微镜探索了添加的MAs的影响,以确定ASTM晶粒度数(G)和掺杂铝合金中金属间化合物的百分比。对于掺有标称含25 mol%TiB 2的MA的Al样品,观察到更高的显微硬度(97.64 H V 0.05)。
