首次采用物理和化学分析方法对Ti-TiNi-HfNi-Hf合金的熔融结晶区进行了研究。液相线表面由六个初生相结晶区组成：λ1，η，δ，θ，β和α。最大的磁场为δ相和β相。λ 1三元相是由包绕反应l + δ → λ1形成的。在Ti-TiNi-HfNi-Hf固相线表面上存在五个涉及液相的恒定平衡。构造了液相线表面、垂直截面和合金结晶图。
Physical and chemical analysis methods are used for the first time to examine the Ti-TiNi-HfNi-Hf alloys in the melting-crystallization region. The liquidus surface is shown to consist of six fields of primary phase crystallization: λ1, η, δ, θ, β, and α. The largest fields are of δ-and β-phases. The λ1ternary phase is formed by peritectic reaction l + δ → λ1. There are five invariant equilibria involving liquid on the Ti-TiNi-HfNi-Hf solidus surface. The liquidus surface, vertical sections, and alloy crystallization scheme are constructed.
