“…As a result, measured scratch depths from the same samples were reduced from ~15 to less than 5 µm (see Figure 3 b). A remarkable effect of heat treatment (austenitization followed by aging) on the mechanical characteristics (hardness, fracture toughness) and the scratch resistance of TiC-30 vol% 17–4 PH (AISI Type 630 steel) cermets with a precipitation hardenable stainless steel binder was also shown in [ 49 ]. These results indicate substantial influence of the metallic binder structure and properties on the wear performance even at comparatively low volumetric fractions.…”

“…Mainly fixed abrasive tests (ASTM G132), single abrasion tests/scratch tests (ASTM G171) and also block-on-ring low-stress abrasion tests (employing adapted ASTM B611 approach) have been used for the study of two-body abrasive wear of cermets [ 38 , 39 , 40 , 41 , 42 , 46 , 47 , 48 , 49 ]. High-temperature two-body loose abrasive tests of cermets have been performed in [ 43 , 44 , 45 ].…”

“…Scratch tests with different applied loads of 10–100 N with a Rockwell conical diamond indenter (tip radius of 200 µm) sliding in linear motion across the flat test sample surface were recently used by a research group of Dalhouse University [ 38 , 49 ]. They studied TiC with nickel aluminide binder (TiC-30 vol% Ni 3 Al) cermets produced by in situ reaction sintering of TiC, Ni and Al powders.…”

WC-based hardmetals are employed widely as wear-resistant ceramic–metal composites for tools and wear parts. Raw materials supply, environmental concerns and some limitations of hardmetals have directed efforts toward development of alternative wear-resistant composites–cermets. We present a current state of knowledge in the field of ceramic-rich (≥50 vol%) cermets behavior in abrasion and erosion conditions, which are the dominant types of wear in many industrial applications. Distinction is made between two-body and three-body abrasion, solid-particle erosion, and slurry erosion. Cermets, in particular TiC-, Ti(C,N)- and Cr3C2-based composites and hardmetals, are compared for their abrasive and erosive wear performance and mechanism. The review enabled formulation of tribological conditions in which cermets may be comparable or have potential to outperform WC-Co hardmetals. Hardmetals, in general, outperform cermets in abrasion and solid-particle erosion at room and moderate temperatures. However, cermets demonstrate their potential mainly in severe conditions—at elevated temperatures and corrosive (oxidation, electrochemical corrosion) environments.

“…However, with the intensification of market competition, the cost of steel needs to be further reduced, alloy reduction has become the focus of research, and Ti has been widely considered as a cheaper microalloying element. In recent years, the influence of Ti on phase transition, precipitates and properties have been widely studied [1][2][3] .…”

Ti is a relatively inexpensive alloying element. Ti micro-alloying enables steel to have higher strength, which has already been applied to steel products in many domains, including engineering machinery. In this work, the effects of cooling temperature upon the mechanical properties and microstructure of Ti microalloyed steel were researched by OM, TEM, tensile and impact tests. The consequences show that as the final cooling temperature (FCT) decreased, the steel plate microstructure changed from PF + P + B (less) to GB + PF (less)+ P (less), and the grain size decreased obviously. As the temperature further decreased to 607°C, the intragranular dislocation tangles and subgrains increased significantly. The size and number of large TiC precipitates in the steel plate decreased with the decrease of the final cooling temperature. Additionally, the mean size of precipitates decreases gradually. As the FCT varied between 672°C and 645°C, the steel plate strength and low temperature toughness were significantly improved. As the temperature is further reduced to 607°C, the strength increase was reduced. Due to the improvement of grain uniformity, the low temperature toughness was further enhanced to 156 J.
