“…[5][6][7][8] Designers and engineers prefer 17-4PH stainless steel because of its beneficial properties such as high strength, hardness, easy modification by heat treatment, and corrosion resistance at temperatures below 300 °C. 6,9,10 This is attributed to the alloy containing more chromium and nickel. 4,11 However, PSM could not previously be used to produce high-density parts from 17-4PH powder due to the poor compressibility of the powder.…”

A review on the production of 17-4PH parts using press and sinter technology

et al. 2023

View full text Add to dashboard Cite

The press and sinter method remains the standard among powder metallurgy processes for powdered stainless-steel materials. It delivers low cost, low oxidation rate, and adequate corrosion resistance. Furthermore, 17-4PH is a martensitic stainless-steel that is commonly used for high-strength and medium-ductility stainless steel parts. However, a few studies have investigated the press and sinter method for producing 17-4PH parts. This shortage is due to the high hardness (low compressibility) of 17-4PH powder. Thus, the main objective of this study is to evaluate the press and sinter method in terms of the manufacturing process, the influencing factors, and the theoretical basis of press and sinter methods in conjunction with metal injection molding technology for the production of 17-4PH parts. First, the literature and monographs are examined and summarized to cover the previous results, research progress, development trends, and applications of press and sinter method 17-4PH parts. Following the theoretical analysis, the practical investigation was conducted by producing parts with cold pressing from 800 to 1600 MPa, followed by sintering: the sintering temperature was 1200 °C for one hour under a protective vacuum atmosphere. ImageJ analysis was performed to measure the sinter density. The results showed an increase in relative sinter density from 84.43% to 96.43% for 800 and 1600 MPa, respectively, while the earlier results reached 93.47%. Overall, the press and sinter method enables the production of high-hardness 17-4PH parts with a high density, without using additives like lubricants, wax, or alloying elements.

“…However, the effective connection between ceramics and metals has become an urgent problem to be solved. It can be found from previous studies that many scholars have studied the connection mechanism between ceramics and metals and obtained excellent composite materials [9][10][11]. However, the ceramics have good stability, thus some conventional solders are difficult to effectively wet the ceramic surface, so the connection between ceramic and SS cannot be realised [12,13].…”

In this paper, the joining of ZrO2 ceramic and 304 stainless steel (SS) was realised by laser offset welding with AgCuTi filler metal. The heat was transferred from the molten pool to the solder through the unmelted SS. AgCuTi would diffuse to form eutectic products with low melting point, forming metallurgical reaction zone. The unmelted SS was retained by laser migration to avoid the mixing of molten solder and molten pool, which reduced the content of brittle phase in the joint. In addition, the crack-free welded joint with a tensile strength of 71 MPa was obtained. The elemental diffusion model was used to simulate the interfacial microstructure changes, and the microstructure was reasonably predicted by changing the welding parameters.

“…However in a published report Wang et al have investigated TLP joining of 17-4-PH stainless steel and Ti(C, N)-based cermet joint which were vacuum brazed with nickel-based filler metal AMS 4777. They found out that by increasing the brazing temperature from 1050 to 1150 °C, the quantity of the brittle constitutes in the brazing seam decreased gradually [18].…”

Transient Liquid Phase Bonding of 17-4-PH Stainless Steel Using Conventional and Two-Step Heating Process

2020

View full text Add to dashboard Cite

Conventional and two-step heating transient liquid phase bonding (TLP) experiments of martensitic precipitation hardening stainless steel 17-4-PH were studied employing AMS 4777 braze filler at temperature of 1050 °C for different times (15 to 90 min) to accomplish the ideal brazing condition. The effect of TLP methods and bonding conditions on the microstructure and shear bond strength was investigated. The critical bonding time for isothermal solidification in conventional and two-step heating TLP was 60 min and 45 min, respectively. The microstructure of isothermal solidification zone consisted of Ni-rich solid solution phase. Eutectic constituents Cr-rich boride and Ni 3 Si were formed in the joint centerline in the athermally solidified zone. In the conventional method planar interface was formed, however in TLP bonding under temperature gradient non-planar interface was formed, high angel grain boundaries merged at the end of isothermal solidification and homogenous bond was produced. Due to the decrease of athermally solidified zone the shear strength increased by increasing the holding time and when using the two-step heating process because of better metal to metal contact, the shear strength was higher. The optimum condition was a temperature gradient TLP in 60 min bonding time, which led to shear strength of 435 MPa.
