PROCESS FOR MANUFACTURE OF A LOW ENERGY REFERENCE PROOF BODY FOR CHARPY IMPACT TEST AND REFERENCE TEST BODY SO OBTAINED

摘要

Process for the manufacture of a body and low energy reference proof for the Charpy impact test and reference body thus obtained. This invention refers to a process for the manufacture of a low -energy test body for a Charpy impact test comprising a heat treatment step (300) with simple and low -complexity sub -steps (310 to 360),And provides a low -energy reference body that can be tested at room temperature. The heat treatment step (300) proposed by this invention comprises the heating of a steel bar at approximately 900 0C temperature for approximately 60 mm. (310);The air bar cooler (320);A new heat step of the bar at a temperature of approximately 870 0C by about 60 mm. (330);The temperature of the oil bar (340);The revenged at a temperature about 300 0C by about 120 mm. (350) and new oil rod tempering (360).
