Effect of Titanium on Gouging Abrasion Behavior and Hardness of Austenitic Manganese Steel

Abstract

The gouging abrasion resistance, hardness and microstructural properties of austenitic manganese steel were investigated as influenced by the varying amount of titanium addition. The gouging abrasion of the steel sample with 0.1 % titanium had the least amount of material loss and showed the highest work hardening effect. The alloying process to 0.2 % was detrimental to its mechanical properties. There was an increase in the hardness from 0 to 0.1 % titanium addition and a decrease at 0.2 % titanium content. Metallurgical surface examination of the unmodified austenitic manganese steel revealed the formation of manganese sulfide micronodules and grain boundary carbide. The titanium modified austenitic manganese steel showed titanium-containing precipitates, which increases the strength and toughness of the steel material as well as the resistance of the material to slip and plastic deformation through the precipitation hardening and grain size refinement mechanisms.

The Relationship between Knowledge and Dietary Habit with Incidence Chronic Energy Deficiency in the Pregnant Women in the Working Area Talise City of Palu

“…According to research by Palimbo et al (2016), regarding the relationship between knowledge and attitudes of pregnant women to the incidence of chronic energy deficiency, it can be seen that the incidence of chronic energy deficiency is still relatively high, as much as 74.2% (6). Also, according to research by Ausa (2016), with the title of research on the relationship between diet and economic status with the incidence of chronic energy deficiency in pregnant women, it is known that there is a relationship between diet (7).…”

Effect of titanium and nitrogen inoculation on the microstructure, mechanical properties and abrasive wear resistance of Hadfield Steels

“…Despite the consolidated literature regarding the production (Subramanyam et al, 1990;Kuyucak, 2004;Kuyucak et al, 2004) and studying of the deformation mechanisms (Adler et al, 1986;Canadinc et al, 2008;Chen et al, 2017;Dastur;Leslie, 1981;Sehitoglu, 2010; present in Hadfield steels, the relationship between microstructural aspects, such as grain refinement and precipitates, as well as wear resistance are not yet well established. Some authors suggest that the addition of titanium results in grain refinement for Hadfield steels and the increase of wear resistance as a result of a finer microstructure (Limooei;Hosseini, 2012;Magdaluyo et al, 2016;Najafabadi et al, 2014). The precipitation of Ti(C, N) could contribute to the increase of nucleation sites, and consequently, finer microstructure (Kucharczyk et al, 2003).…”

Revisiting gouging abrasion test for jaw crushers

“…Some recent investigations deserved attention for the microstructural aspects of this alloy and its performance being tested in terms of wear (Silva, 2004;Olawale et al, 2013;Magdaluyo et al, 2016). Considering the wear performance of a wide range of materials and hardfacing deposits during gouging abrasion test, the findings described by Llewellyn et al (2006) can be considered a very useful guide.…”
