“…It is best to utilize the characteristics of quenching residual stress evolution and quench-induced phase transformation during quenching to design the quenching technology. Nallathambi et al [17] studied the influence of thermal, metallurgical, and mechanical properties on the final distortion and residual stresses during quenching. However, the effect of material properties on the evolution of residual stress at different temperatures is still unclear.…”

“…In most cases, compressive residual stresses near the surface of the tools are favoured. The origin of residual stress can be divided into three categories: mechanical, thermal, and metallurgical [2]. Shot peening or grinding are examples for mechanically induced residual stresses where plastic deformations occur near the surface.…”

“…La distorsión producida en un acero cuando es sometido a un proceso termo-mecánico se origina por la presencia de varios factores de naturaleza térmica, mecánica y microestructural que influyen conjuntamente e interaccionan de manera simultánea (Canale y Totten, 2005;Arimoto et al, 2009;Nallathambi et al, 2010). En la mecánica del continuo la distorsión se analiza por medio del campo de deformaciones del material.…”

“…La transformación empieza y termina a unas temperaturas denominadas M S y M F , respectivamente. Por otra parte, la temperatura M S desciende cuando aumenta el contenido de carbono en el acero (Nallathambi et al, 2010) y por lo tanto, los aceros con mayor contenido en carbono tienden a retener más cantidad de austenita. Para calcular el valor de la temperatura M S se utilizan ecua ciones fenomenológicas, como la descrita por Steven y Haynes, (1956), válida para aceros que contengan hasta un 0,5% de carbono en peso (x C = 0,5) (Ec.…”
