TL;DR: The magnetic phase diagram of γ Fe-Mn alloys has been investigated in the whole range of composition by neutron diffraction and other techniques as discussed by the authors, and the results agree qualitatively with the prediction based on the band theory.
Abstract: The magnetic phase diagram of γ Fe-Mn alloys has been investigated in the whole range of composition by neutron diffraction and other techniques. The f.c.c. phase of Fe-Mn alloys with less than 40 at. % iron and more than 85 at. % iron was stabilized by addition of small amounts of copper and carbon respectively in the alloys. An antiferromagnetic long range order was detected in the whole range composition. The antiferromagnetism of this alloy system Fe x -Mn 1- x was found to be classified into three distinct groups according to the composition. They are 1) 0≤ x ≤0.3, 2) 0.4≤ x ≤0.8, and 3) 0.8≤ x ≤1. The magnetic phase of the second group is markedly different from other two groups. The results agree qualitatively with the prediction based on the band theory.

TL;DR: The effects of various metallic ions using various metallic powders on the relative growth ratio of fibroblasts L929 and osteoblasts MC3T3-E1 cells were carried out and the new Ti-15%Zr- 4%Nb-4%Ta-0.2%Pd alloy exhibited a higher corrosion resistance in physiological saline solution.

TL;DR: In this article, the authors used transmission electron microscopy (TEM) and extended X-ray absorption fine structure (EXAFS) to characterize the surface electronic state of the as-prepared samples and found that boron donated electron to nickel in Ni-B alloy, resulting in electron-enrichment of elemental Ni.

TL;DR: In this paper, a set of model FeCrAl alloys containing 10−20Cr, 3−5Al, and 0−0.12Y in weight percent, were prepared by conventional arc-melting and hot-working processes to explore the effect of composition on the properties of FecrAlY alloys.

TL;DR: In this article, the feasibility of friction stir welding (FSW) of steel has been investigated and it has been shown that the mechanical properties of FSW of 12% chromium alloy and low carbon steel joints compare favorably with the properties of the parent metal.
Abstract: The feasibility of friction stir welding (FSW) of steel is demonstrated. Tensile and bend testing have confirmed that the mechanical properties of friction stir welded 12% chromium alloy and low carbon steel joints compare favourably with the properties of the parent metal. Some initial feasibility studies of FSW of both 12% chromium alloy and low carbon steel are described. Although more development work is needed, particularly to improve tool materials, the prognosis for continued developments in FSW of steel is shown to be good.
