So many results that aren't mine?
References in many bibliographies are sometimes referred to as "Surname, I", so the citations of academics whose Surname and initials are the same may occasionally interfere. This problem is often the case with citation indexes all over the world.

Abstract:

Aluminium is one of the basic materials used in many sectors, especially in automotive, defence and aviation. Generally, aluminium parts are manufactured by using injection molding methods in many sectors, such as automotive, etc. Injection presses that are used for die-casting material have a lot of parameters, affect the molded parts’ properties. In this study, the effect of injection parameters on the mechanical properties was investigated. Firstly, a test part that is shaped currently on the injection press machine in a sector was found out. An aluminum alloy, named Al〖Si〗_12 Cu (EN AC 47000), that is used widely in die-casting techniques was preferred. Three injection parameters, such as, injection velocity (m/s), time of the mold opening (s) and molten metal temperature (0C), were selected. And all works were planned with the full factorial experimental design method. Thus, the test parts were manufactured by using an injection molding machine. Moreover, many tests, such as hardness and tensile, were performed on the test parts to investigate the effect of injection parameters on the mechanical properties of the material. The tests were analysed with the full factorial and ANOVA method. As a results of the analysis, the highest hardness value was obtained as 85 HB when the molten metal temperature was 750 ℃, the injection velocity was 1.3 m/s, the mold opening time was 10 s, and the highest breaking strength was obtained as molten metal temperature 725 ℃, injection velocity 4 m/s, when the mold opening time was 12 s was found to be 264 MPa.
