Additive manufacturing (AM) has revolutionized the manufacturing sector, particularly with the advent of 3D printing technology, which allows for the creation of customized, cost-effective, and waste-free products. However, concerns about the strength and reliability of 3D-printed products persist. This study focuses on the impact of three crucial variables—infill .Impact testing is commonly performed using methods such as the Charpy and Izod tests, which involve striking a notched specimen with a swinging pendulum to measure energy absorption. The results of impact testing help in selecting materials for applications where resistance to sudden forces is crucial, such as in construction, automotive, and .
KEYWORDS: Steel, Additive manufacturing, Impact, Fatigue INTRODUCTION . Charpy impact test as a commonly used . conditions are kept same. Table 1 covered several preliminary studies on charpy impact energy of AM materials including 316L (Yasa, Deckers et al. 2010, Zhong, Liu et al. 2016, Brytan 2017), . Laser-based metal additive manufacturing has the potential to be applied in the production of parts for safety-critical applications (e.g., aircraft components, armor and military applications), where materials must be able to absorb energy before breaking. Charpy impact testing is a standardized method used to assess the toughness of metals. The process is repeated layer after layer until the 3D model is complete. The Charpy and Izod impact tests are used to determine the object's hardness, surface roughness, and impact strength. The Charpy test specimen ASTM A370 (Fig. 3) and the Izod test specimen ASTM D256 (Fig. 4) were used. In the present study, instrumented impact strength tests were carried out on Charpy AlSi10Mg samples produced using laser additive manufacturing in order to accurately investigate the influence of .
At present, the methods to improve the toughness of alloys include adjustment of alloy composition [21], heat treatment [22], and TWIP.According to Hrabe et al. [23], an increase in the α lath thickness contributed to a higher Charpy impact absorbed energy after the EBM TC4 alloy was annealed in the α+β region.Changfu Li et al. [24] claimed that fracture toughness of . The most common testing method to obtain this property is the Charpy impact test, which measures the energy absorbed by a material during the fracture of a specimen [Citation 7]. Although achieving high-quality parts is possible, the complexity of the parametric setup makes it challenging to anticipate material qualities precisely before .2 ASTM E2248-15, “Standard Test Method for Impact Testing of Miniaturized Charpy V-Notch Specimens,” ASTM Book of Standards, Vol. 03.01, ASTM International, West Conshohocken, PA, 2015. .
