Abstract

Research results for the production of strips from a platinum‒rhodium alloy for the manufacture of spinneret feeders are presented. Using the author’s software, an analysis of the process of rolling strips of the investigated alloy with a thickness of 1 mm from a forged workpiece with a thickness of 28 mm, which is currently used in industrial conditions, was carried out. The number of rolling passes and the number of annealing steps decreased. Experiments for the process of cold sheet rolling of strips from the platinum‒rhodium alloy were carried out. The proposed compression mode was tested under industrial conditions, and it was found that for the studied process of cold sheet rolling of a platinum‒rhodium alloy, it is possible to increase the unit degree of deformation to 0.3–0.4 mm, which leads to a decrease in the fractional deformation, a decrease in the number of anneals and passes in the absence of strip destruction.

工业用Pt-Rh合金薄板的力学性能和失效准则分析

介绍了用一种铂铑合金生产喷丝板给料机用带钢的研究结果。利用作者的软件，对目前工业条件下使用的厚度为28 mm的锻件轧制厚度为1 mm的合金带的工艺进行了分析。轧制道次和退火步骤减少。对铂铑合金带材冷轧工艺进行了试验研究。在工业条件下对所提出的压缩方式进行了试验，结果表明，在所研究的一种铂铑合金冷轧过程中，可以将单位变形程度提高到0.3 ~ 0.4 mm，从而在不破坏带材的情况下减少了分数变形，减少了退火次数和道次。

期刊介绍： The Journal publishes and disseminates original research in the field of material forming. The research should constitute major achievements in the understanding, modeling or simulation of material forming processes. In this respect ‘forming’ implies a deliberate deformation of material. The journal establishes a platform of communication between engineers and scientists, covering all forming processes, including sheet forming, bulk forming, powder forming, forming in near-melt conditions (injection moulding, thixoforming, film blowing etc.), micro-forming, hydro-forming, thermo-forming, incremental forming etc. Other manufacturing technologies like machining and cutting can be included if the focus of the work is on plastic deformations. All materials (metals, ceramics, polymers, composites, glass, wood, fibre reinforced materials, materials in food processing, biomaterials, nano-materials, shape memory alloys etc.) and approaches (micro-macro modelling, thermo-mechanical modelling, numerical simulation including new and advanced numerical strategies, experimental analysis, inverse analysis, model identification, optimization, design and control of forming tools and machines, wear and friction, mechanical behavior and formability of materials etc.) are concerned.
