A titanium alloy contains vanadium, from 10 to 20% by weight; aluminum, from 0.2 to 10% by weight; and a balance essentially titanium, and the alloy has a microstructure including a martensite phase. Alternatively, the titanium alloy contains vanadium, from 10 to 20% by weight; aluminum, from 0.2 to 10% by weight; and a balance essentially titanium, and the alloy has a microstructure including a &#x3b2; phase capable of transforming into a martensite phase by cold working or cooling under a room temperature.

Titanium alloy of low Young's modulus

This present invention relates to an alloy comprising Sn, at least one of Ti and Zr and at least one of Nb and Ta as the major elements. The total percentage of the Nb and Ta in the alloy material is preferably from 8 to 20 atom % and the percentage of the Sn in the alloy material is preferably from 2 to 6 atom %. The alloy material is preferably Ni-free and has shape memory characteristics or superelasticity.

Ternary alloy and apparatus thereof

A magnetic alloy which contains not less than 0.03 weight percent but not more than 5.0 weight percent of P, not less than 0.01 weight percent but not more than 5.0 weight percent of at least one element of Ti, Nb, and Zr, not less than 2.5 weight percent but not more than 10 weight percent Si and the remaining part consisting mainly of Fe is disclosed. In the alloy, P is segregated on the grain boundaries thereof with a specified amount which results in a superior magnetic characteristics and workability represented by the fact that the alloy can be rolled.

Magnetic alloy

A magnetic alloy which contains not less than 0.03 weight % but not more than 5.0 weight % of P not less than 3.0 weight % but not more than 26.0 weight % of Al and Si totally (where Al is not less than 0.01 weight % but not more than 13.0 weight % and Si is not less than 0.01 weight % but not more than 13.0 weight %), the remaining part of the alloy consists mainly of Fe and the alloy is characterized in that P is presented on the grain boundary thereof with the amount more than 0.5 weight % of the atoms which form said grain boundary.
