Manufacturing Process Fundamentals

Raw Material Selection and Preparation

The journey of AMS 4911 titanium plate begins with meticulous raw material selection. High-purity titanium alloy sourcing is paramount, as the quality of the final product directly correlates with the initial material composition. At Baoji JL Clad Metals Materials Co., Ltd., we maintain stringent control over raw material specifications, ensuring each batch meets the required chemical composition. The material undergoes thorough inspection and testing before entering the production line, with density measurements confirming the standard 4.43 g/cm³ specification. Our facility's advanced testing equipment verifies material properties, including tensile strength targets of ≥990 MPa and yield strength of ≥860 MPa, establishing a solid foundation for subsequent processing steps.

Melting and Forming Operations

The melting process represents a critical phase in AMS 4911 titanium plate production, utilizing state-of-the-art vacuum furnaces to maintain material purity and prevent contamination. Our sophisticated melting operations ensure uniform composition throughout the material, while carefully controlled temperature gradients prevent structural defects. The molten titanium undergoes multiple refining stages, removing impurities and ensuring consistent alloy distribution. This phase requires precise control of environmental conditions, as titanium's high reactivity necessitates stringent atmospheric control to prevent oxidation and maintain material integrity throughout the forming process.

Surface Treatment and Quality Control

Final surface treatments play a vital role in achieving the desired specifications for AMS 4911 titanium plate. Our facility offers various surface finish options, including mill finish, polished, and pickled surfaces, each requiring specific processing techniques. The quality control process involves comprehensive testing procedures, including ultrasonic inspection, mechanical property verification, and dimensional accuracy checks. Each plate undergoes rigorous examination to ensure compliance with ASTM B265, ASME SB-265, and AMS 4911 standards, with particular attention to maintaining the specified elongation of ≥10% across the entire surface area.

Advanced Processing Techniques

Heat Treatment and Microstructure Control

Heat treatment of AMS 4911 titanium plate requires precise temperature control and timing to achieve optimal mechanical properties. Our advanced heat treatment processes utilize computer-controlled furnaces that maintain exact temperature profiles throughout the entire cycle. The process begins with solution treatment at carefully selected temperatures, followed by controlled cooling rates that promote desired microstructural development. This sophisticated approach ensures uniform property distribution across plates ranging from 0.5 mm to 100 mm in thickness, while maintaining strict adherence to industry standards for material performance and reliability.

Precision Rolling and Dimensional Control

The rolling process represents a crucial stage in achieving the precise dimensions required for AMS 4911 titanium plate. Our facility employs both hot-rolling and cold-rolling techniques, utilizing advanced rolling mills capable of handling widths up to 3000 mm and lengths up to 6000 mm. The rolling sequence involves multiple passes with carefully controlled reduction ratios, ensuring uniform thickness distribution and optimal surface quality. Temperature control during hot rolling is particularly critical, as it directly influences the material's final mechanical properties and microstructural characteristics.

Advanced Testing and Certification

Our comprehensive testing protocols ensure that every AMS 4911 titanium plate meets or exceeds industry standards. The testing regime includes non-destructive evaluation techniques, mechanical property verification, and detailed microstructural analysis. Each plate undergoes thorough dimensional inspection using precision measurement equipment, ensuring compliance with customer specifications.
