      镁是目前轻量化效果最显著的节能金属材料、未来最有潜力的清洁能源及绿色储能材料之一。镁基复合材料（MMC）指以镁金属及其合金为基体，与一种或几种金属或非金属增强体相结合而制成的一种复合材料，或者叫指含有镁元素的化合物或者是镁元素与其他元素组成的化合物组合包括氢氧化镁、合成水滑石、硅酸镁等，镁基复合材料是同类金属基复合材料中比强度和比模量最高的一种,同时尺寸稳定性好，广泛应用在汽车高铁、芯片、农业膜、航空航天、生物医学以及消费电子等。

      按照增强体不同，镁基复合材料又分为碳纳米管增强镁基复合材料、颗粒增强镁基复合材料、晶须增强镁基复合材料、氧化铝纤维增强镁基复合材料、硼纤维增强镁基复合材料以及碳纤维增强镁基复合材料。

      镁基复合材料企业通常招聘的职位除常规的研发管理岗位外，还有压铸项目经理、注册安全工程师、镁基储氢材料工程师、技术部长、压铸模具开发工程师、 压铸工艺、生产总监 、质量管理总监等。

     Light-weight magnesium which possesses extremely low density, good machinability and structural properties, can meet the requirements of energy saving and emission reduction in the transportation sector and other automotive application

    Magnesium matrix composites (MMCs) share presenting unique and excellent properties that any component does not have, such as high specific stiffness and specific strength, good dimensional stability, outstanding shock absorption performance, excellent electromagnetic shielding and hydrogen storage characteristics, etc.

    There are various types of particulate reinforcements available to prepare magnesium matrix composites (MMCs) such as carbides (SiC, TiC, B4C, ZrC), oxides (Al2O3, TiO2), borides (ZrB2, TiB2), nitrides (AlN, BN, ZrN, TiN) and metals (Ti, Cu, Mo, Ni) . It has been shown that the MMCs containing one or more traditional micron size particulate reinforcements and continuous magnesium matrix have outstanding advantages over monolithic magnesium, such as high strength, high modulus and wear properties

     Magnesium matrix composites firms often offer job vacancy except normal researchers and executives include pressure casting project manager、certified safety engineer、hrdrogen storage engineer of MMCs、technical director、die casting mould develoment enginner、production director、quality control director ,etc.
