This article presents a critical overview of the current failure mechanisms and treatment
methods applied to improve the surface integrity of die tools used in hot forging process. The …

The severe operation conditions of the hot working process lead to premature failure of the
hot working tools. The dominant failure of hot working tools is wear of the tool surfaces …

The lifetime of dies used for production of forged parts is variable and determined by wear
rate, plastic deformation, thermal and mechanical fatigue. These tools are subjected to …

This paper describes the phenomena taking place on the surface of the dies used for hot
forging. Because of this paper's limited space only changes in the tool surface layer during …

The influence of nitriding time in the wear behaviour of an AISI H13 hot work steel used on
forging dies has been studied. AISI H13 steel was nitrided by a patented sursulf bath …

High temperature reciprocating sliding wear experiments of a Ni-based superalloy pin
against a cast iron disc were performed at 600 and 800° C (load: 20 N, frequency: 20 Hz …

Cold metal transfer (CMT) welding is a new gas metal arc welding process having several
advantages such as low heat input and spatter free welding. This makes it of great …

Abstract Additive Layer Manufacturing (ALM) processes are attracting interest in the forging
industry due to their potential suitability for remanufacturing and repair of tools and dies. The …

Dry sliding wear of metals is strongly affected by the formation of oxide particles and their
incorporation into compacted oxide layers, so-called glaze layers. A high-temperature …

The paper presents a comprehensive review of the most popular methods used for hot
forging tools to increase their durability. The main directions of development of methods for …
