The casting defects were analysed by X-ray non-destructive testing and the buoyancy method. It can be found that the compactness of casting is greatly improved by vibration. In the solidification feeding, according to vibration theory, P-wave will play a decisive role. When the transmission direction of P-wave is perpendicular to the feeding direction, it will lead to the alternation of dense-sparse state in the solidification system. When feeding is blocked, in the sparse state, the diameter of the feeding channel will increase, so that the pressure loss of feeding decreases. At the feeding end, the feeding pressure will make the solidification feeding again. On the contrary, vibration can’t further promote the feeding in the dense state.","PeriodicalId":13939,"journal":{"name":"International Journal of Cast Metals Research","volume":"33 1","pages":"177 - 183"},"PeriodicalIF":1.4,"publicationDate":"2020-08-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/13640461.2020.1804168","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46100048","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although the original invention defined the specific two-stage deformation scenario, almost four decades of extensive research, involving a variety of ferrous and non-ferrous alloys, subjected to conventional and severe plastic deformations, caused its evolution. According to present understanding, any deformation of cast structures with a strain level sufficient to trigger recrystallisation leads to dendrite-to-globule transition during subsequent partial melting. It is proposed that the SIMA term should not only be associated with the particular deformation scenario but should be seen as a broad synonym for a variety of thermomechanical treatments, explored for controlling the solidification microstructure. Such an updated definition expands applicability of the SIMA concept from bulk billets to coarse particulates and fine powders.","PeriodicalId":13939,"journal":{"name":"International Journal of Cast Metals Research","volume":"33 1","pages":"157 - 164"},"PeriodicalIF":1.4,"publicationDate":"2020-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/13640461.2020.1801561","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45325070","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Encouraging results in terms of strength and hardness are obtained by testing the standard sand samples. In fact, the properties exhibited are almost similar to the values obtained by addition of 2% dextrin as an additive to the sand aggregate.

The adhesion of the epoxy coating on the cast iron surface firstly depends on the roughness of the surface; polished samples showed high adherence by comparison with as-received samples.

It was determined that the layer is composed of chromium carbide (Cr7C3), ledeburite and pearlite.

Results showed that wear rate increases linearly with increase in load and sliding velocity whereas with increased sliding distance, it increases non-linearly with reduced slope. Minimum wear is observed at optimum combination of load (10 N), velocity (1 m/s) and sliding distance (500 m). Worn surfaces were analysed using scanning electron microscope to determine the wear mechanisms.

However, a higher shake-out temperature might also lead to increased residual stresses due to faster cooling. In order to get a good agreement between simulated and measured temperature curves it is important to adjust material data and heat transfer coefficients accordingly. A reduction of the thermal conductivity of the sand by 25% and a drastically increased HTC were the main adjustments. From the residual stress simulation, the most important lesson learned was the necessity to include the sand in the calculation. Especially internal sand cores can greatly restrict the thermal contraction of the casting. After this fine-tuning of the simulation a good agreement with measurements was obtained. It could be verified that an increased shake-out temperature will lead to significantly increased residual stresses.","PeriodicalId":13939,"journal":{"name":"International Journal of Cast Metals Research","volume":"33 1","pages":"112 - 119"},"PeriodicalIF":1.4,"publicationDate":"2020-05-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1080/13640461.2020.1766279","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"60012025","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
