Characteristics of adiabatic shear bands in the orthogonal, cutting of 30CrNi3MoV steel

Mechanism of Chip Formation in High-Speed Turning of Inconel 718

“…This causes thermal softening of the chip material in primary deformation zone. Therefore, shear strength of the material within a narrow band along A 1 B 1 reduces and becomes less than the original strength of the work material (Duan and Wang, 2005). At this instant, crack initiates at B 1 and propagates toward tool tip approaching D 2 approximately 3=4th the mean height of the chip as shown in Figure 8a.…”

“…At this instant, crack initiates at B 1 and propagates toward tool tip approaching D 2 approximately 3=4th the mean height of the chip as shown in Figure 8a. Further tool movement causes frictional shear at an angle / 2 along A 2 D 2 (Duan and Wang, 2005). The cycle continues and further segments S 2 , S 3 , S 4 , etc.…”

An analytical model to predict specific shear energy in high-speed turning of Inconel 718

“…(19). In the literature, value of Taylor-Quinney coefficient is taken as 0.9 for Titanium alloy [12] and (0.85-0.95) for other alloys [36,37]. Therefore, in this model, this coefficient is assumed to be 0.9.…”

Microstructure evolution of adiabatic shear band in AZ31 alloy under dynamic compression

“…Adiabatic shear band (ASB) is usually considered to be a precursor of material failure and damage during dynamic deformation processes, such as high-speed impact [1], punching [2], cutting [3], and friction stir welding [4]. Adiabatic shear phenomenon is widely found in Ti alloys [5,6], stainless steels [7][8][9], Al alloys [10], metallic glass [11], magnesium alloys [12,13], etc.…”
