| dc.description.abstract | This study investigated the effects of grain size variations on the microstructure and mechanical properties of austenitic manganese steels (X120Mn12), which were cast in sand and permanent moulds. The effects of the mould type on the grain size of the alloys cast without heat treatment were determined. While the permanent mould alloy was cooled in open air after casting, the sand castings were cooled in the mould. In addition to measuring the grain size, OM (Optical Microscopy), XRD (X-Ray Diffraction), XRF (X-Ray Fluorescence), SEM, EDX (Energy-Dispersive X-Ray Spectroscopy), hardness, tensile, and impact tests were performed on the produced alloys. The permanent mould had a higher cooling rate, and therefore, the samples cast in it had a more refined grain structure. Thus, we could obtain a grain structure that was likely to exhibit the desired properties. Permanent mould casting resulted in 4.46% lower hardness, 46.15% higher tensile strength, 12.30% higher yield, and 52.84% lower elongation than sand casting. The notch impact test value was 1.18% higher, while the surface roughness (Ra) was 8.98% lower in the sand mould samples than in the permanent mould samples. The sand mould samples wore 53.48% more in the abrasive wear test. Cette & eacute;tude a examin & eacute; les effets des variations de taille de grain sur la microstructure et les propri & eacute;t & eacute;s m & eacute;caniques des aciers aust & eacute;nitiques au mangan & egrave;se (X120Mn12), coul & eacute;s dans des moules en sable ou permanents. On a d & eacute;termin & eacute; les effets du type de moule sur la taille de grain des alliages coul & eacute;s sans traitement thermique. Tandis que l'on a refroidi & agrave; l'air libre l'alliage coul & eacute; en moule permanent, on a refroidi les pi & egrave;ces coul & eacute;es en moule de sable dans le moule. En plus de la mesure de la taille des grains, on a utilis & eacute; la MO (microscopie optique), la diffraction des rayons X (DRX), la fluorescence des rayons X (XRF), la microscopie & eacute;lectronique & agrave; balayage (MEB), la spectroscopie de rayons X & agrave; dispersion d'& eacute;nergie (EDX), ainsi que des essais de duret & eacute;, de traction et de r & eacute;silience sur les alliages produits. Le moule permanent pr & eacute;sentait un taux de refroidissement plus & eacute;lev & eacute;, et par cons & eacute;quent, les & eacute;chantillons coul & eacute;s dans ce moule avaient une structure granulaire plus fine. Ainsi, nous avons pu obtenir une structure granulaire susceptible de pr & eacute;senter les propri & eacute;t & eacute;s souhait & eacute;es. Le moulage en moule permanent a donn & eacute; lieu & agrave; une duret & eacute; inf & eacute;rieure de 4.46%, une r & eacute;sistance & agrave; la traction sup & eacute;rieure de 46.15%, une limite d'& eacute;lasticit & eacute; sup & eacute;rieure de 12.30% et un allongement inf & eacute;rieur de 52.84% par rapport au moulage en sable. La valeur de l'essai de r & eacute;silience apr & egrave;s entaille & eacute;tait sup & eacute;rieure de 1.18%, tandis que la rugosit & eacute; de surface (Ra) & eacute;tait inf & eacute;rieure de 8.98% dans les & eacute;chantillons moul & eacute;s en sable par rapport aux & eacute;chantillons moul & eacute;s en moule permanent. Les & eacute;chantillons du moule en sable ont subi une usure sup & eacute;rieure de 53.48% lors de l'essai d'usure abrasive. | |
