TL;DR: In this article, a method of producing a ultra fine grain steel made of ferrite having a mean grain size of not larger than 3 mu m as the base phase, after ingoting raw materials, by austenitizing the ingot by heating it to a temperature of at least an Ac 3 point, then, applying compression working of a reduction ratio at least 50% at a temperature from an Ae 3 point or lower to an Ar 3 point - 150 DEG C, or at least 550 DEGC, and thereafter, cooling, wherein the strain rate as compression working

TL;DR: In this paper, the effect of microstructural change during ageing and creep on elastic modulus was investigated in ferritic steels and the elastic moduli of aged, crept and serviced (service-exposed) materials were investigated.

TL;DR: In this article, the deformation microstructures were studied in a two-phase (about 60% ferrite and 40% austenite) Fe -27%Cr -9%Ni stainless steel.

TL;DR: In this paper, a variant selection of bcc-Cr at the grain boundaries in a supersaturated fcc matrix was studied using a Ni-43Cr alloy, and the preferentially selected variant was examined as a function of the grain boundary misorientation, the tilt angle between the {111}fcc plane and the boundary plane, and orientation relationships with respect to both of the adjacent matrix grains.
