摘要： PROBLEM TO BE SOLVED: To inexpensively provide a smelted high-rigidity ferroalloy obtained through being melted in the atmosphere.
SOLUTION: The smelted high-rigidity ferroalloy comprises a matrix which is obtained through melting and solidifying a raw material and contains Fe as the main component, and highly rigid particles which are dispersed in the matrix and have higher rigidity than the matrix has. The highly rigid particle comprises one or more main alloy elements selected from among the element group consisting of 5a group elements (Nb and Ta) and 6a group elements (Cr, Mo and W), and a composite boride of Fe and boron (B). The smelted high-rigidity ferroalloy does not contain an element having high reactivity with oxygen and nitrogen in the atmosphere (Ti or the like), so that it can be melted in the atmosphere and acquire sufficiently high Young's modulus.

摘要： PROBLEM TO BE SOLVED: To provide a new high rigidity iron based alloy in which rigidity can be efficiently increased, and also mechanical properties can be improved.
SOLUTION: The high rigidity iron based alloy is composed of: a matrix composed of pure iron or an iron alloy; and dispersed grains composed of boride crystallized out into the matrix and dispersed. The dispersed grains are boride grains composed of titanium (Ti) and at least one kind of other boride grains composed of one or more elements selected from the group VIa elements and iron (Fe), and the boride grains composed of Ti are contained in the amount of an eutectic composition or below in a pseudo two-dimensional phase diagram of the metal composing the matrix and the boride of Ti. By suppressing the content of the boride grains composed of Ti (e.g., to ≤13 vol.%), and jointly using the other boride grains, high rigidity can be realized while suppressing the coarsening of the boride grains.
