It was shown that the complex character of the thermograms is mainly due to the difference in the rate of destruction of individual morphological components of the eggshell. The comparative contribution of each micro-nanostructural morphological components of the eggshell (mamillary, palisade, and crystalline layers) in the integral yield of carbon dioxide (CO2) as a product of eggshell thermal destruction at specific temperatures was shown. The activation energies (Ea) for individual shell components were calculated. The theoretical foundations for the development of the method for the analysis of nano- and microstructural components of eggshells have been developed.

Thus, several companies implement such technologies.

Hence, this paper develops three aspects for the AM supply chain evaluation: At first, a literature review about supply chain and costing literature is conducted. Secondly, five scenarios for the internal production (make) and four scenarios of external supply (buy) are proposed. As a third aspect, a benchmark study, which is based on 140 quotes from AM suppliers, provides insights in external supply costs for LPBF manufactured parts.","PeriodicalId":6770,"journal":{"name":"2020 IEEE 10th International Conference Nanomaterials: Applications & Properties (NAP)","volume":"PP 1","pages":"02SAMA14-1-02SAMA14-6"},"PeriodicalIF":0.0,"publicationDate":"2020-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84607114","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}

Structural transformations, concentration changes of chemical elements, grain and subgrain structures, dislocation density, size and volume fraction of phase precipitates, causes of crack formation in treated surface layers under various alloying regimes have been studied by the methods of optical, analytical scanning, and transmission electron microscopy. It was found that the tendency to crack formation of samples after laser alloying is due to structural (crystallite size, shape factor) and concentration changes associated with redistribution of elements, in particular, chromium. Noticeable changes in the structural-phase state of the treated surfaces are observed for an optimal mode of laser alloying. This laser alloying regime is characterized by a uniform distribution of dislocations with a general decrease in their density. The sizes of phase precipitates in the surface layers are more dispersed and evenly distributed in the internal volumes of grains. These are nanoparticles with a size of 40…100 nm and larger phase precipitates (up to 1 $mu$m).","PeriodicalId":6770,"journal":{"name":"2020 IEEE 10th International Conference Nanomaterials: Applications & Properties (NAP)","volume":"799 1","pages":"02IT01-1-02IT01-4"},"PeriodicalIF":0.0,"publicationDate":"2020-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85450840","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}
