Estudo da microestrutura de um aço mola após passar por tratamento térmicos e forjamento através da técnica da cutelaria

Abstract

The main objective of this course completion project was the analysis of the microstructure of a vehicle coil spring, which underwent a transformation process to obtain a blade using a technique called cutlery making. This technique involves forging, tempering, and annealing as means of producing cutting instruments. The cutting instrument discussed in this work is a knife. The expected final result of the microstructure is tempered martensite. T empered martensite provides hardness with a touch of ductility and makes the cutlery piece a durable and resistant tool for use. The pieces obtained through this process require a high level of skill and knowledge, as the temperatures used vary according to the chemical composition.
