Substantial　in　situ　TiC　precipitation　in　high-titanium　steel　can　significantly　enhance　its　wear　resistance.　This　improvement　is　attributed　to　the　high　hardness,　low　density,　large　precipitation　volume,　and　stable　chemical　properties　of　TiC,　which　has　attracted　increasing　attention.　This　paper　firstly　summarizes　the　recent　research　progress　on　the　solute　redistribution　model,　kinetics,　and　thermodynamic　calculations　of　TiC　precipitation,　as　well　as　the　relevant　experimental　research　on　high-titanium　steel　prepared　by　the　melting　cast　method.　It　provides　a　detailed　analysis　of　the　microstructure,　mechanical　properties　including　hardness,　tensile　strength,　yield　strength,　elongation　and　impact　toughness,　and　other　properties　of　high-titanium　steel,　highlighting　the　influencing　factors.　Additionally,　the　wear　resistance　and　wear　mechanisms　of　high-titanium　steel　with　different　Ti　content　under　different　wear　conditions　are　compared,　including　two-body　wear,　three-body　wear,　lubrication　wear,　and　impact　wear.　At　last,　the　future　potential　research　directions　for　high-titanium　steel　are　proposed,　aiming　to　provide　support　for　further　development　and　application.
