heat of formation of an intermetallic and the milling energy required for its formation during mechanical alloying. This has been demonstrated in case of B2 intermetallic compounds, namely, NiAl, FeAl, CoAl and MnAl. The milling energy corresponding to the start of formation of the compounds during mechanical alloying of the elemental blends is found to decrease linearly with the heat of formation of the
摘要 本文试图得出金属间化合物的形成热与其在机械合金化过程中形成所需的铣削能量之间的关系。这已经在 B2 金属间化合物,即 NiAl、FeAl、CoAl 和 MnAl 的情况下得到证明。发现与元素混合物的机械合金化过程中化合物开始形成相对应的研磨能量随着金属间化合物的形成热而线性降低,使用 Miedema 模型计算。还合成了 Al 3 Zr、Ni 3 Al、Ni 3 Mn、CoFe、NiTi、Zr 3 Co,以尝试在更广泛的化合物范围内以及混合焓测试假设的强度。已尝试了解化合物形成的机制。
