Abstract: A method for producing a corrosion resistant metal substrate and corrosion resistant metal substrate provided thereby. The method involves forming a plated substrate including a metal substrate provided with a nickel layer or with a nickel and cobalt layer followed by electrodepositing a molybdenum oxide layer from an aqueous solution onto the plated substrate, which is subsequently subjected to an annealing step in a reducing atmosphere to reduce the molybdenum oxide in the molybdenum oxide layer to molybdenum metal in a reduction annealing step and to form a diffusion layer which contains nickel and molybdenum, and optionally cobalt.

Abstract: The present invention relates to ordered Alloy 690 with improved thermal conductivity. By maintaining Alloy 690 in a temperature range of 350-570° C. for a proper amount of time, the atomic arrangement is controlled to properly form the ordered phases. The ordered phases formed in the ordered Alloy 690 increases its thermal conductivity due to a low thermal scattering effect of the ordered phase as observed in pure metals.

Abstract: A magnetic core includes alloy phases 20 each made of Fe-based soft magnetic alloy grains including M1 (wherein M1 represents both elements of Al and Cr), Si, and R (wherein R represents at least one element selected from the group consisting of Y, Zr, Nb, La, Hf and Ta), and has a structure in which the alloy phases 20 are connected to each other through a grain boundary phase 30. In the grain boundary phase 30, an oxide region is produced. The oxide region includes Fe, M1, Si and R and further includes Al in a larger proportion by mass than the alloy phases 20.

Abstract: A method of making an alpha-beta titanium alloy is provided. The method includes forming a melt and solidifying the melt to form an ingot. The melt composition includes concentrations of Al from about 4.7 wt. % to about 6.0 wt. %; V from about 6.5 wt. % to about 8.0 wt. %; Si at less than 1 wt. %; Fe at up to about 0.3 wt. %; 0 at less than 1 wt. %; and a balance of Ti and incidental impurities. Furthermore, the Al/V ratio in the melt is equal to the concentration of the Al divided by the concentration of the V in weight percent is from about 0.65 to about 0.8.
