Review Paper on Development of Nano Inserts for Machining HRSA Materials for Aerospace Applications

In the current scenario, cutting tool industries use powder material tungsten carbide of 60-80 microns grain size to produce inserts. There are a lot scopes improve properties materials enhance their ability machine challenging like heat resistant super alloys (HRSA). Reducing nano level may help increase strength, substrate hardness, Fracture toughness, and thermal conductivity insert. This review studies different strategies used develop powders for application. We observed that most focused on latest in carbide, boron which reduced as powders, pressed, sintered with techniques hot isostatic pressing (HIP), Spark plasma sintering. Finally, research gaps future challenges understanding development applications critically discussed, providing an interpretation possible directions scientific this field.
