“…In all the samples, the WHdecreased rapidly in stage 1 and increased quickly in stage 2, whereas the variation in WH in stage 3 and 4 was different. The first stage is mainly associated with the deformation of ferrite, the variation of WH instages 2 and 3is attributed to TRIP effect [13,16,17,19].The decrease inWH in stage 4 is primarily resulted from the weak TRIP effect.…”

In the context of obtaining high strength-high ductility combination in transformation induced plasticity (TRIP) steels, we underscore the practical significance of controlling the mechanical stability of austenite and transformation mechanisms during deformation. The steel subjected to tensile deformation near temperature exhibited excellent combination of tensile strength and ductility, which is attributed to the synergistic effect of stress-assisted transformation and strain-induced transformation. The calculated temperature was in good agreement with the experimental results.

“…Rock drill steel requires appropriate strength and hardness, high surface wear resistance, and good toughness . From the point of view of production technology, these properties can be achieved through an optimized heat treatment . 23CrNi3Mo, a Cr–Ni–Mo steel, is widely used as rock drill steel at present, which can be heat‐treated to obtain a good combination of strength and toughness by austenizing, quenching, and tempering, because it contains the alloying elements such as Cr, Ni, and Mo, which promote high hardenability .…”

This research investigates the mechanical properties of a Cr-Ni-Mo-alloyed rock drill steel tempered at different temperatures from 150 to 550 C. The highest strength, hardness, and impact energy occur when the steel is tempered at 180 C. Strength, hardness, and impact energy decrease with increasing tempering temperature from 180 to 400 C. For tempering temperatures higher than 400 C, the steel exhibits: 1) an increase in impact energy; 2) an increase in strength and hardness when tempered at 420, 450, and 480 C; and 3) a gradual decrease in strength and hardness when tempered at temperature higher than 480 C. The mechanism of the changes of impact energy and hardness with tempering temperature is proposed.

We elucidate here the mechanistic contribution of the interplay between microstructural constituents and plastic deformation behavior in hot-rolled Fe-0.2C-11Mn-xAl steels containing 2-6 wt.% Al. The decrease in austenite fraction with increase in Al-content was accompanied by decrease in tensile strength, while the δ-ferrite content and ductility increased. 2Al steel was characterized by ultrahigh ultimate tensile strength (UTS) of 1407 MPa, while 6Al steel exhibited extremely high total elongation (TE) of 65%. The superior ductility in 6Al steel is attributed to cumulative contribution of transformation induced plasticity (TRIP) effect and twinning induced plasticity (TWIP) effect. The increase in soft δ-ferrite phase with low microhardness led to increase in TE and decrease in UTS and work hardening rate.
