“…In another study Katsina substantiated the role of intercritical thermal cycling to improve toughness of API‐5L grade steel. Intense structural refinement of HAZ in ferritic‐austenitic steel weldment was reported by Bondareva et al that led to substantial enhancement of impact toughness. Other than ferrous system, thermal cycling of 2195Al friction stir‐weld resulted in a decrease in dislocation density and precipitation of second phase within and along the grain boundaries…”

In this research work intercritical thermal cycling is adopted on a cost‐effective material (AISI 1010 steel) so as to attain a hierarchical structure at multiple length scales, from nanometer scale onwards. As a consequence, a considerably high strength (UTS = 1 GPa) along with a significant ductility (% Elongation = 15) is achieved. This is attributed to a novel microstructure that consists of nano‐sized cementite particle dispersed α‐ferrite islands in a matrix of nano‐sized cementite particle dispersed highly sub‐structured martensite (containing both “lath” and “plate” morphology). The substructure appears in the form of dislocations in lath martensite and nanoscale twins in plate martensite. The α‐ferrite islands provide intrinsic ductilization through microvoid coalescence; while extrinsic ductilization is attributed to crack arrest at dimples and crack deflection at hard plate martensite matrix. Such a high strength is obtained by virtue of martensitic strengthening (through generation of highly substructured martensite) and nano‐dispersion strengthening (due to presence of dispersed nano‐sized cementite particles).

“…Thus, in the temperature interval from 20 to 400 °C, the growth of a valid reduction occurs mainly due to the high-rise deformation of titanium VT1 0; in this case the closest approach altitude of deformation of the composite's components is observed at temperature of 400 to 450 °C [7].…”

Received by explosion welding titanium-aluminum billet can be subjected to various operations of metals processing by pressure, which results in change of metals mechanical properties and the arrangement of the layers. The work investigated the influence of temperature on the deformation ability of titanium-aluminum layer composites by rolling. It is revealed that the deformation capacity of the layered titanium-aluminum composite is determined by the plastic properties of aluminum layers at the temperature of rolling. At 450 °C a sharp increase in strain capacity of titanium-aluminum composite is revealed.

“…Each graph refers to one of three characteristics of the zones in the thickness of the crimped ring: at the striker, at the middle of the ring thickness, at the mandrel. The distribution of deformations near the striker is more influenced by the degree of deformation, in the middle part of the ring thickness, the deformation effect of various tool shapes is more noticeable at the degree of compression ε0H > 10 %, and near the mandrel -at all degrees of compression, the geometry's influence of the rolling tool is noted [9][10][11][12].…”
