“…As the current studied steel is iron‐based alloys with high carbon content, one of the main remedies for these issues is conventional heat treatments [6]. Accordingly, a homogeneous microstructure consisting of a hardened matrix with acceptable mechanical characteristics, in terms of hardness/toughness and dimensional stability, has been achieved thanks to conventional heat treatments [7].…”

The present work examines the effects of pack‐boronizing treatment on the surface characteristics of modified industrial cold‐work tool steel intended for polymer crushing. Particular attention is paid to optimizing the process parameters to improve the tool surface properties and thus achieve a satisfactory tool life. To this end, a series of samples were subjected to boronizing treatment within the temperature range from 800 °C to 1000 °C for soaking periods of 2 h, 4 h, 6 h and 8 h. The structural and mechanical properties of the modified metal surface were analyzed using optical and scanning electron microscopy, x‐ray diffraction, microhardness testing and pin‐on‐disk tribotesting. The adhesion quality of the boride layer‐substrate was carried out using the adhesion test Daimler Benz Rockwell‐C. The corrosion properties were determined by the electrochemical polarization method. Experimental results showed that the optimum temperature‐temporal conditions of 900 °C/4 h that are the intermediate processing parameters led to a better compromise between the intended properties, in terms of resistance to wear and corrosion, as well as adhesion quality.

“…STD-11 tool steel is generally used for materials of stamping tools in the automotive industry and is comparable to SKD-11 (JIS G 4404), D2 (ASTM A 681-08), and 1.2379/X153CrMo12 (DIN EN ISO 4957). The mechanical properties of D2 tool steel are summarized in Table 2 [39]. In order to harden the STD-11 tool steel by introducing a martensite microstructure, heat treatment was performed as shown in Figure 1.…”

Efficient Wear Simulation Methodology for Predicting Nonlinear Wear Behavior of Tools in Sheet Metal Forming

et al. 2022

In conventional wear simulation, the geometry must be updated for succeeding iterations to predict the accumulated wear. However, repeating this procedure up to the desired iteration is rather time consuming. Thus, a wear simulation process capable of reasonable quantitative wear prediction in reduced computational time is needed. This study aimed to develop an efficient wear simulation method to predict quantitative wear reasonably in reduced computational time without updating the geometry for succeeding iterations. The wear resistance of a stamping tool was quantitatively evaluated for different punch shapes (R3.0 and R5.5) and coating conditions (physical vapor deposition of CrN and AlTiCrN coatings) by using a progressive die set. To capture the nonlinear wear behavior with respect to strokes, a nonlinear equation from a modified form of Archard’s wear model was proposed. By utilizing the scale factor representing the changes in wear properties with respect to wear depth as input, the simulation can predict the behavior of rapidly increasing wear depth with respect to strokes after failure initiation. Furthermore, the proposed simulation method is efficient in terms of computational time because it does not need to perform geometry updates.

In this experimental work D2 and D3 type cutting tool samples have hot forged and heat treated. The belt a drop hammer of weight 500N was employed to press forge the selected steel tool materials. In the forging operation the materials were heated to 1100°C-1200°C. The structures of hot forged and heat treated tool samples were observed through metallurgical microscope. The hardness and impact strength of the tool materials were studied using Vickers micro hardness tester and Charpy impact testing machine. The wear resistance of the tool materials was assessed using pin on disc wear tester at constant sliding speed (1.675m/s) and sliding distance (1005m) at room temperature condition. The hardness, impact strength and wear resistance of the 20% forged and heat treated D2 tool and D3 tool materials were found comparatively better and the same was discussed under the background of microstructural changes.
