What is Metallurgy and Material Science?
Metallurgy and Material Science is the scientific study of metals, their alloys, processing techniques, microstructures, and properties including corrosion, wear, and mechanical behavior.
This field encompasses 49,020 works with a focus on corrosion behavior, microstructure, cavitation erosion, tribocorrosion of nickel-aluminium bronze alloys, and machinability of lead-free brass alloys. Key areas include surface modification and friction stir processing. Growth rate over the past five years is not available.

Why It Matters
Metallurgy and Material Science enables development of alloys resistant to corrosion and wear for marine and industrial applications, such as nickel-aluminium bronze used in propellers prone to cavitation erosion. Friedel (1958) in "Metallic alloys" analyzed alloy structures foundational to modern materials design, cited 1783 times. Kubaschewski and Hopkins (1953) in "Oxidation of metals and alloys" detailed oxidation mechanisms affecting alloy durability, cited 1350 times, informing protections in high-temperature environments like turbines. Sieradzki and Newman (1987) in "Stress-corrosion cracking" examined cracking in alloys, cited 465 times, critical for pipeline and aerospace safety.

Frequently Asked Questions
What is mechanical alloying in metallurgy?
Mechanical alloying is a process to produce alloys by high-energy ball milling of elemental powders. Benjamin (1976) in "Mechanical Alloying" introduced it for creating materials unattainable by melting, cited 515 times. Gilman and Benjamin (1983) in "Mechanical Alloying" reviewed its applications in dispersion-strengthened alloys.
How does oxidation affect metals and alloys?
Oxidation forms oxide layers on metal surfaces, influencing corrosion resistance and high-temperature performance. Kubaschewski and Hopkins (1953) in "Oxidation of metals and alloys" provided thermodynamic data on oxide stability, cited 1350 times. This guides alloy selection for oxidative environments.
What causes stress-corrosion cracking in alloys?
Stress-corrosion cracking results from combined tensile stress and corrosive environment leading to brittle failure. Sieradzki and Newman (1987) in "Stress-corrosion cracking" modeled anodic dissolution at crack tips in brass and steel, cited 465 times. Mitigation involves alloy composition adjustments.
What are glassy metals in material science?
Glassy metals are amorphous metallic alloys lacking crystalline structure, offering high strength and corrosion resistance. Herman and Libby (1981) in "Glassy Metals I" surveyed their preparation and properties, cited 728 times. They apply in magnetic and biomedical devices.
What is the role of zinc diffusion in brass alloys?
Zinc diffusion in alpha brass governs homogenization and phase stability during processing. Smigelskas (1947) in "Zinc diffusion in alpha brass" measured diffusion coefficients, cited 845 times. This informs heat treatment for uniform microstructures.
How does friction stir processing modify alloy surfaces?
Friction stir processing refines microstructure through severe plastic deformation without melting. It applies to nickel-aluminium bronze for improved cavitation erosion resistance. This technique enhances surface properties in lead-free brass machinability studies.
