Metamorphosis quality preparing of alloy Ti64 in laboratory conditions

Purpose: The aim of our research was the developing of the method for preparing titanium alloy (Ti64 ELI) by remold in laboratory conditions on our research workplace. As a reason for writting the paper is to inform the technical society. Design/methodology/approach: The objectives were achieved by using differently sources heating of remolded titanium alloy Ti64 ELI, by using of differently conditions by vacuum melting and pouring in to ceramics or copper moulds. As main method used for our research was remolding, purification, casting in the vacuum and then special heat treating by HIP processes. The quality of microstructure was investigated by electron microscopy and tested by Charpy impact test. The mean aim was to get microcastings of very intricate shapes and with very high quality of casting material. Through application four differently conditions of remolding we have found that in our workplace we have good ability to prepare the microcastings with very good quality, which is the main conclusion. Findings: For expectation it is possible by using such a process for production special microcastings from Ti64 ELI alloy. The mean idea of this paper will have practical implications. Research limitations/implications: In this time as a limitation is a little small capacity of plasma burner. Practical implications: The result of this paper should be made some changes in practice e.g. as savings of turning and lastly the using of Rapid Prototyping method. Originality/value: The original value of our paper is the testimony above quality of alloy Ti64 ELI as cast. The quality of alloy Ti64 ELI as cast is comparable with certified Ti64 ELI from abroad. The reach a destination of outcome in our laboratory conditions is a perspective method for production of microcastings from alloy Ti64.
