Introduction
Powder bed fusion (PBF-LB) additive manufacturing of aluminum alloy parts has been widely adopted in aerospace, new energy vehicles, and other fields due to its excellent comprehensive performance.
Lightweight aluminum alloys are widely used in additive manufacturing for mass production in fields such as [list of fields]. Commonly used additive manufacturing aluminum alloy grades include AlSi10Mg, AlSi7Mg, AlMgScZr, and [list of alloys].
AlMnMgScZr. With the increasing demands on the comprehensive performance of aluminum alloy materials under service conditions, including strength, elastic modulus, high-temperature resistance, wear resistance, and corrosion resistance...
With continuous improvement, aluminum alloy-based composite materials have received widespread attention and have become an indispensable part of advanced materials.
Components.
Aluminum-based composite materials possess high strength, high specific modulus, low density, good high-temperature performance, as well as high wear resistance, fatigue resistance, and low coefficient of thermal expansion.
With numerous advantages such as good thermal conductivity, additive manufacturing of aluminum involves composite materials such as particulate reinforcement, whisker reinforcement, and fiber reinforcement. Currently, additive manufacturing of aluminum...
The most commonly used reinforcements in composite materials are particulate reinforcements, including titanium diboride (TiB2) and titanium carbide (TiC).
Incorporation or in-situ formation can effectively suppress defects such as hot cracking and porosity that are very easy to occur in aluminum alloys during the PBF-LB process, such as...
The method of incorporating TiB2 as a reinforcement into AlZnMgCu aluminum alloys (the commonly used grade in additive manufacturing aluminum alloy powder is 7075) is as follows.
By regulating grain morphology, increasing heterogeneous nucleation sites, improving material formability, reducing defect content, and significantly enhancing composite material properties;
The mechanical properties and high-temperature resistance of AlSi10Mg alloy can be improved by incorporating TiC reinforcement.
Since aluminum-based composite materials have been applied in many industries, this document, in its formulation, focused on those currently in widespread use.
Technical requirements, test methods, and references are also provided for composite parts of AlSi10Mg and AlZnMgCu aluminum alloys with added TiB2 and TiC.
Microstructure photographs, especially showing the compositional range of particulate reinforcement in aluminum matrix composite parts, are provided to facilitate additive manufacturing of aluminum matrix composites.
The rapid development of materials technology. The technical specifications for AlSi10Mg and AlZnMgCu-based composite materials proposed in this document apply to other grades.
The aluminum-based composite materials can serve as a reference.
