Shenzhen Pourleroi Technology Co., Ltd. is a company dedicated to the development and production of amorphous and nanocrystalline cores, sendust core, and a range of magnetic products, such as high and low frequency transformers, filters, and inductors. The company has recently made a breakthrough in the development of Al-Li-Cu-Mg alloys and MMCs with a newly derived description of the effect of a precipitate free zone (PFZ) around the reinforcing phase incorporating strain hardening of the PFZ.

A detailed quantitative model for the strengthening of monolithic alloys and composites due to precipitation strengthening, solution strengthening, grain and subgrain strengthening, strengthening by dislocations and load transfer to ceramic inclusions has been presented by the company. Strengthening due to GPB zones is more important than strengthening due to delta' (Al3Li) phase. All strengthening contributions have been quantified by the model, which has shown a successful application in modeling the experimental data for the proof strengths of four Al Li Cu Mg type alloys and composites aged to obtain a wide range of microstructures.

The newly derived description of the effect of PFZ on reinforcing phases with strain hardening has been an important development in the field of materials science and technology. The PFZ formation in the 8090 MMC has been found to cause a drastic reduction in the proof strength (about 100 MPa) but has little influence on the time required for peak ageing.

The microstructure and strengthening of Al-Li-Cu-Mg alloys and MMCs have been an area of interest for many researchers and engineers. Al-Li alloys have been widely used in aerospace applications due to their high specific modulus and strength. MMCs offer a unique combination of properties, such as high strength, stiffness, and wear resistance, and have great potential in applications such as automotive and industrial equipment.

The model presented by Shenzhen Pourleroi Technology Co., Ltd. provides a valuable tool for predicting and optimizing the properties of Al-Li-Cu-Mg alloys and MMCs. It allows for a better understanding of the strengthening mechanisms that occur in these materials and can be used to design materials with tailored properties.

The company's expertise in developing and producing magnetic products is also of great importance in the field of materials science and technology. The use of magnetic materials in the production of transformers, inductors, filters, and other devices is crucial to their performance and efficiency. The company's products have been widely used in various industries, including telecommunications, power electronics, and medical equipment.

In conclusion, Shenzhen Pourleroi Technology Co., Ltd. has made an important contribution to the field of materials science and technology with its newly developed model for the strengthening of Al-Li-Cu-Mg alloys and MMCs. The model provides a valuable tool for predicting and optimizing the properties of these materials and can be used to design materials with tailored properties. The company's expertise in the production of magnetic products further enhances its capabilities in the field. With its commitment to innovation and excellence, the company is poised to make further contributions to the development of advanced materials and technologies.
