“…The schematic diagram of vertical rolling of metal powder/wire mesh composite is shown in Figure 2 (b). After adjusting the gap at the bottom of the powder delivery box, fill the metal powder inside the box [6] . When the rolling machine and ultrasonic generator are synchronously turned on, the wire mesh is driven and continuously moves downwards by the frictional force due to the reverse rotation of the two rolling rolls.…”

Porous metal materials are applied in various industries, among which powder rolling is the most widely used process for preparing porous metal materials. Then, metal porous materials prepared solely from powder as raw materials have the disadvantage of low mechanical properties, while wire mesh as reinforcement can effectively improve tensile strength. The preparation process of wire mesh powder composite is complex and requires the addition of adhesives. In this article, the mechanical properties of thin metal strips prepared by powder and wire mesh composite vertical rolling were much higher than those prepared by pure powder. Moreover, this thin strip had porous characteristics, and the preparation process was simple and easy to promote. This research could provide a reference for the powder metallurgy field, especially for the preparation of metal porous materials by vertical rolling.

“…Therefore, the prediction and prevention of damage and fractures during material forming processes have always been a focal point of international research. [1][2][3][4][5] Scholars from different countries have carried out a significant amount of research on the micro mechanisms, fracture criteria, and process optimization related to damage and fracture in metal materials. [6][7][8][9][10][11] These studies involve various materials, different forming methods, diverse damage patterns, and distinct fracture criteria.…”

In metal rolling processes, internal holes or cracks can result in unqualified products. This paper evaluates the possibility of cracking in three-roll planetary rolling of bismuth-containing stainless steel bar by combining experiments, finite element simulations, and theoretical modeling. Stress-strain data obtained from hot compression experiments were used to draw hot processing maps after modification. The prediction results of several standard ductile fracture criteria were compared, and it was found that the Ayada criterion could accurately predict the size and location of rolled section cracks during the rolling process. The study also investigated the effects of three key forming parameters: billet temperature, strain rate, and friction coefficient on the percentage of damaged area. Results showed that billet temperature had a significant influence on crack initiation followed by strain rate. A mathematical model with damage value as its target was established using a three-way cubic polynomial regression analysis for these parameters' interaction effect on crack initiation and development. By calculating extreme values for this function based on optimized process parameters, a set of optimum processes with minimal risk for initiation cracking was obtained. Field rolling results confirmed no cross-sectional cracks according to these optimized process parameters.
