Companies with special product requirements are looking toward combining the unique properties of special alloy classes with the geometrical benefits of additive manufacturing (AM). In this contribution a method for rapid multiparameter optimization for Laser Powder Bed Fusion in Metals (PBF-LB/M) is described. Parameter sets for multiple quality features such as surface roughness, down face integrity, mechanical performance, and bulk density are optimized simultaneously using compact Design of Experiment approaches. The method is demonstrated on a case component with requirements on weldability, corrosion resistance, and mechanical resistance which led to the need for rapid powder manufacturing and printing parameter optimization in stainless steel 310S-an alloy not typically available on the PBF-LB market. The method resulted in rapidly developed processing parameters for 310S producing high-quality parts befitting the requirements of the case component. The result showcases the potential for short lead times and product development using simple Design of Experiment approaches for materials and parameter development within PBF-LB/M.","PeriodicalId":72352,"journal":{"name":"Berg- und huttenmannische Monatshefte","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10230487/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9583595","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

From a mining perspective, these transformations mean a continued growing demand for raw materials, which must be met by extracting mineral raw materials from primary deposits. However, increased quantities with \"business as usual\" would also increase the environmental and social impacts of mining, which is not an option, especially in Europe and Austria.Due to these facts, there is a need for research on new and improved mining methods and planning, as well as on optimised processes and machinery. This article describes how the Chair of Mining Engineering and Mineral Economics at Montanuniversität Leoben intends to use these challenges as an opportunity with its updated strategy, both for research and for teaching. For the research area, sustainability and involvement in the shaping of raw materials policy should form the framework. With a focus on digitisation and underground mining as well as strengthening the areas of open-pit mining, conveying technology and geoinformatics, research is to be future-proofed for these upcoming transformations. Teaching will continue to include a basic engineering education with specialisation in mining, whereby digitalisation will play an increasingly strong role.","PeriodicalId":72352,"journal":{"name":"Berg- und huttenmannische Monatshefte","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9880356/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10821020","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Berg adapted the plays into a single three-act structure and made other changes in the names of characters and their attributes, and he titled his opera Lulu, after the central figure. The subject matter of the opera was highly controversial, with a perverse eroticism and sordid violence. Given the political climate of the early 1930s, prospects for a performance of the work were dim. The chronology by which Berg created the libretto for Lulu and its music reveals many delays that suggest a struggle on the composer’s part in grappling with the subject and with his relatively new twelve-tone method of composing. Berg completed the basic compositional work for the opera in spring 1934, and he then created a concert suite from the work, much as he had done with Wozzeck, which he titled Symphonic Pieces from the Opera “Lulu.” The necessary revisions to the opera that Berg foresaw and most of the orchestration of Act 3 remained incomplete at the time of his death in December 1935, and the opera was performed in its entirety only in 1979. In Lulu Berg fully developed his own distinctive twelve-tone method of composing but continued to invoke traditional musical forms.","PeriodicalId":72352,"journal":{"name":"Berg- und huttenmannische Monatshefte","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73406585","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
