摘要： The disclosure provides methods of making iron-based alloys, as well as resulting alloys. An iron-based alloy containing a small amount of nickel (e.g., 0.5 to 2.0 wt %) is annealed and machined. The alloy is sufficiently ductile to reduce the likelihood of cracking, while not sufficiently high to result in a hardened alloy. After the alloy is shaped, the alloy is hardened by nitriding.

摘要： The present invention addresses the problem of providing: a stainless steel which is provided with gas corrosion resistance suitable for substrates of compound thin film solar cells without requiring a surface treatment such as coating or plating; a method for producing this stainless steel; and a compound thin film solar cell which uses this stainless steel as a substrate. In order to solve the above-described problem, the present invention is characterized by forming an Fe—Cr—Al oxide film which has a film thickness of 15 nm or less and contains, in mass %, 0.03% or less of C, 2% or less of Si, 2% or less of Mn, 10-25% of Cr, 0.05% or less of P, 0.01% or less of S, 0.03% or less of N and 0.5-5% of Al, with the balance made up of Fe and unavoidable impurities, and wherein the maximum value of the Al concentration is 30% by mass or more and the Fe concentration at the depth of 2 nm from the surface is 30% or less in the profile of cation fractions excluding O and C ions. In addition, it is preferable that the surface film contains Si and Ti, while satisfying: Si is 0.3% or more; Ti is 0.03-0.5%; and (Mg+Ga) >0.001%. The surface film is obtained by carrying out annealing within the temperature range of 700-1,100° C. in a low-dew-point hydrogen gas.

摘要： The present invention relates to a method of manufacturing of a casted part or ingot of a metallic alloy attaining a minimal segregation in the casting process, for alloys which are prone to segregate. The method can also be employed to refine the grain and microstructure of the obtained alloys. The method is especially interesting for Fe, Ti, Co or Ni based alloys. The method is very inexpensive and can be applied for the obtaining of very large cross-sections. An additional feature of the method is that it can be employed to capitalize impurities.
