基于γ-TiAl相的合金(仅次于TiAl)可以被认为是介于陶瓷和耐热合金之间的合金，TiAl的最大优点是尽管重量轻(比重为4)却具有优异的高温强度，但其主要缺点是脆性。因此，所施加的应力与重量成比例的旋转部件是最合适的应用。此外，在减轻重量直接改善设备性能的情况下，应该补偿TiAl的缺点。本部分介绍了TiAl在客车涡轮增压器中的首次商业应用。
alloys based on γ-TiAl phase Gtereafter TiAl) can be thought of as intermediate between ceramics and heat-resistant alloys, The grent-est merit of TiAl is excellent high-temperature strength in spite of its light weight (specific gravity of 4) while its chief disadvantlage is brittleness. Accordingly, a rotating component in which applied stress is in proportion to weight is the most suitable application. Furthermore, in cases where weight reduction directly improves equipment performance, the disadvantage of TiAl should be compensated. This repart describes the first commercial application of TiAl in a turbocharger for passenger vehicles.
